RAILWAY-TIE.

Specification of Letters Patent. Patented Oct, 19, 1920.

Application filed January .26, 1920. Serial No, 354,125.

To all QU/LOWL it may concern.

Be it known that I, ADoLPHUs Y. CLARK, of Short Creek, in the county of Mohaveand State of Arizona, have invented certain new and useful Improvements in Railway- Ties; and I do hereby declare the following to be a full, clear, and exact desdription' of the same reference being had to the accompanying drawings, forming part of this specification, and to the figures and letters of reference marked thereon.

This invention relates torailway ties in which the body of the tie is made ofmetal and the direct supports for the rails are small cushion blocks of wood or like material, thus securing all advantages of a timber tie with the employment of a, small quantity of wood. The advantages are the sound-deadeningeflect and elastic support of the rails; the ability to secure the rails in place with the ordinary spikes and the insulation of the rails, so as to render them capable of use in the ordinary signaling systems employing track clrcuits.

To this end, the 1nvent1on consists in certain novel details of construction, combinations and arrangements of parts, all as will be now described, and the particular features of novelty being pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a perspective view of a tie em bodying the present invention, one of the locking members being shown removed from the tie body.

Fig. 2 is a similar'view of block seat or chamber, removed from the tie body.

Fig. 3 is a transverse section shpwing the cushion block and its chamber secured in the tie body.

Fig. 4 is a modified form of construction, one of the locking members being removed from the tie body.

Fig. 5 is a detail view of the cushion block the cushion of metal, thus form possess a certain inherent resiliency which will relieve the rolling stock from vibrations incident to a rigid roadbed but toincrease this eifect the rails are not supported directly on the metal portions of the tie, but upon cushion blocks B. To economize in the amount of metal material required in the construction of the tie, the present invention contemplates the provision of a cushion block seat or chamber C in which the cushion blocks B are secured. Chambers C are secured in a trough-like body or tie in any preferred manner, the chambers in the present instance being shown as provided "with a'pluralityof .tongues 0 which are adapted to extend through openings 0 in the bottom A of the tie and are bent back against saidibottoin V The blocks are fitted in the chambers O in proper position to receivethe rails and are of such length as will afford sufiicient strength to support therails and retain the rail fastening means, such as ordinary spikes. These blocks are preferably formed of wood and are held down in place in the tieand chamber by shoulders 0 formed by slotting the. sides 0 of the chambers C as at c to form tongues c .which are turned down over the top of the blocks B as shown in Figs. 1 to 4. In the form'shown in Figs. 6 and 7, the tops of the chambers are cut away to form two transverse straps 0, which embrace the top of the cushion blocks B. The chamber C in which the cushion blocks are seated, permits'the sides A of the trough like body to be made relatively low, and by forming the cushion .bloc'kretaining ext-ensions on the chambers insteadiof on the sides A of the tie, the entire tie body can be formed from a comparatively narrow sheet greatly decreasing the cost of the ties. r

Longitudinal. movement of the cushion blocks in the tie body is prevented by plates D fitting within the trough-like body at each end'of the block and interlocking with the tie. The plates may be of various forms, two of which have been illustrated. In Fig.

. 1 the plate has lateral extensions cl which fit in slots (Z in the side walls A and the lateral extensions have depending portions at their outer ends which extend down on the outer side ofthe tie body. This form of fastening plate is made more or less resilient so that the dependmg portions of the lateral extensions will firmly grip the sides of the tie body and retain the fastening plate in place without the necessity of employing other fastening means, such as nails or the like, as

shown in the other figures.

In Figs. 4 and 6, the fastening plates D are provided at one end with a lateral extension 03 which extends through an aperture (i in one side of the tie body and at their other end with a lateral extension d which is slotted as at and is adapted to be fitted into aslot d in the other side of the tie body. Vith this construction'the are to be renewed or reversed when worn on one side. V y

In order to permlt any rain water falling 1n the tie body to drain off,an opening F is provided in the bottom A of the tie body.

1 What I claimis:

1. A railway tie comprising a metal trough-like body, a chamber secured in said body, a cushion block seated in the chamber and projecting at the top of the chamber and body to form a 'rail seat, tongues or extensions on the, chamber adapted to be turned down over the top of the cushion block, and transverse holding plates fitting within the trough-like body at each end of the block and having lateral extensions in terlocking with the sides of the trough-like body to prevent relative longitudinal movement of the cushion block and body 2. A railway tie comprising a metal troughlike body, said body having relatively low sides, cushion block chambers secured in said trough-like body, cushion blocks seated in said chambers and projecting an appreciabledistance above the sides of the trough-like body to form rail seats,

tongues .or extensions on the cushionblock chambers adapted to embrace the top of the cushion block and transverse holding plates fitting within the trough-like body. ateach end of the block and having lateral extensions interlocking with the sides of the trough-like body to prevent relative longi tudinal movement of the cushion blocks and 7 body.

3. A railway tie comprising a metal trough-like body, one side of said body having a plurality oi vertical slots therein and ,the other side having a corresponding number of apertures therein disposed opposite sald slots, cushion blocksseated in said troi'igh-like body and projecting at the top of said bod to form rail seats means for y a preventing vertical displacement of said f blocks and transverse-holdin slates havin v i cl a V lateral extensions adapted, to enter the oppoja sitely disposed apertures and slots in the sides of the trough-like body wherebythe plates will-be interlocked with the sides to prevent relative longitudinal movement of Y the block and body. M

t; A railway tie comprising metal trough-like body, one side of saidbody having a plurality of vertical slot's therein and or the other side having a correspondingnumber of apertures therein dlsposed opposite saidslots, cushion block chambers secured in said body, cushion blocks seated in said,

chambers and projecting atithe top otthe chambers and body, to "form rail seat, tongues or extensions on the cushion block chambers adapted to'be turned down over the top ofthe blocks, and transverse holding plates having lateral, extensions adapted to enter the oppositelydisposed apertures and slots whereby the plates will be inter locked with thesides of; the tie body to prevent relative longitudinal'movement oi" the blocks and body; V

5. A railway tie comprising metal trough-like body, cushion block chambers V secured therein, cushion blocks seated in said chambers and projecting at thetop of the chamber'tofform rail seats, means formed on the sides of the chamber for preventingvertical displacement of the cushion blocks, and transverse holding plates fitting within the trough-like body at each end of the blocks and having lateral extensions interlocking with the side of the body to preventrelative longitudinal movement of the blocks and body.
